Age from Sprout: just under 5 months
Soil in pots, Hydroponic, or Coco / Brand and type of Soil & Size of Pots: using ffof in five gallon pots for the last 2 months.
How often do you water and how do you determine when to do so? Depending on stage of growth usually about every 3 to 4 days tops. At the end of flowering they usually get really thirsty though. Lifting them and just feeling the soil via finger.
PH of water and runoff or solution in reservoir: the last few waterings have been right around 6.5-6.8 going in and 6.1-6.4 coming out.
What is strength of nutrient mix? EC, or TDS: I don’t have a Ppm or ec meter, I have successfully grown through harvest 5 different rounds now by using 1/4-3/4 what the recommended doses are on the bottle.
Indoor or Outdoor: indoor
Light system, size and height from plants:
1000 watt hps in a vented hood, the closest the plants get is about 15" but never closer usually the bulk of the canopy sits between 18-20"
Temps; Day, Night: day 74 night, 67-68
Humidity; Day, Night: day 43-45 night 45-49 depending on when it was last watered.
Ventilation system; Yes, No, Size: Yes, 720 cfm pulling through a carbon filter and pushing out through the hood and continuing out the window. All in a 360 cubic foot room. Also have two 16" oscillating fans on the “1” speed setting in the room to keep things moving.
AC, Humidifier, De-humidifier: dehumidifier if anything gets over 50
Co2; Yes, No: no co2
Running botanicare “bloom” for flowering, adding their calmag when necessary- generally in veg and during stretch.
----Okay so I have four plants in the grow room, just staring their 4th week of flower. only one is experiencing what I thought might be a nitrogen deficiency because fan leaves that are exposed to the light were turning yellow and staring to get blotchy brown dots. But at the same time some leaves were showing signs of a nitrogen toxicity, looking dark in their shade of green and also doing the N claw. (Shown in some pics) and lower leaves were also doing this same thing with the yellowing and dots. The effected plant doesn’t seem to be stunted in any kind of growth but the fan leaf problem is definitely spreading. I attached some photos of some effected spots on the plant and also a screen shot of the banner photo from your ILGM’s “Stop nutrient deficiencies in marijuana plants now!” Page, (after googling nitrogen deficiency) which looks to be very similar to my problem, but the photo, like I said was only the banner at the top of the page and wasn’t actually used alongside a description of the problem like all the other really helpful list items on that page.
